No changes made as requated and now on ITC

I have been inside Vodacom stores all the time making payments, the month I made arrangements, everything goes wrong. Debit orders stopped then started a month later. Even when I went in to pay the amount cash in store, they have not told me the debit went off already and I ended up paying double. I have requested to do a swap on contract holders twice, I have asked to freeze the account so it doesn't run high, I have made payment arrangements, I went in to go pay and the machine didn't work, and now after paying what I agreed to pay, I'm handed over to lawyers. Vodacom staff don't know what they are doing, they don't give advice or advance customers into the right direction. Every time I go into the shop there is new staff, I doubt they even have training. Why is it that only Vodacom benefits from my contracts and I don't yet I'm the one paying. I know of more then 10 times I wanted to complain but just let it slide after the last time they credit my account with R7000 I complained. I will never go with Vodacom again. Very quick to take your money but never willing to assist or just even do their work right!!!!!
